A printer by any other name would smell as sweet?<br>
<br>
<br>

<br>
<br>
5.4.4. printer-name (name(127))<br>
<br>
<br>
This REQUIRED Printer attribute contains the name of the Printer. It<br>
is a name that is more End User friendly than a URI. An<br>
Administrator determines a Printer's name and sets this attribute to<br>
that name. This name can be the last part of the Printer's URI, or<br>
it can be unrelated. In non-US-English locales, a name can contain<br>
